Hard to Port and Double Knuckle Port/Starboard doesn't function correctly
 

I am running GWX 3.0 with H.sie's hardcoded fixes. When I order a "Hard to Port / Starboard" my u-boot only dives to 24m and continue to cruise straight ahead according to the plotted route instead of making the 90 turn to port / starboard.

When I order a "Double Knuckle Port / Starboard", my u-boot starts spinning around in an endless loop.

Does anyone know how I can fix the issue?
